Introduction

VrayPattern is a plug-in for 3dsmax and V-Ray

VRayPattern allows to multiply geometry periodically without extra memory consumption. As a

sample you can use any tiled geometry (or those with unobtrusive joints)

VRayPattern also allows to curve geometry on any surface


2/16

The plug-in works in similar way as displacement map. However, displacement map can only

use raster or vector maps of pattern to cover the surface of geometry, VRayPattern can use any

of the original geometry.

The plug-in best used where large amount of geometry required, but without great accuracy. A

few examples.

System requirements

3ds Max versions: 2008, 2009, 2010, 2011, all 32 or 64 bit

3ds Max Design : all

V-Ray versions: V-Ray 1.5 (SP2 and higher), V-Ray 2 - 32 or 64 bit

OS: Windows XP, Windows Vista, Windows 7, all 32 and 64 bit

Please note:

User must have local administrator rights with Windows XP to use VRayPattern.

on Windows 7 administrator rights needed only during installation

Installation


6/16

Please make sure you downloaded latest version of the plug-in from our forum.

Users are provided with the same installation file for both Workstation and Render node

VRayPattern.exe

Workstation can be used only when license is properly installed, and provides access to all

VRayPattern options.

If VRayPattern does not find license file it switches itself to Rendernode mode and only can

render files created with VRayPattern Workstation

Rendering is available both locally and over network.

To install the program you need to run the VRayPattern.exe with the administrator rights.

Dont forget to quit 3ds max before you start the installation.

VRayPattern setup wizard.

Dont forget to quit 3ds max before you start the installation.


7/16

Read carefully the license agreement. If you accept it tick I accept and then press setup

button; if not, press "Cancel" button.

Choose 3ds max version you use.


8/16

Choose V-Ray version you use.

The setup wizard will automatically select destination folder for 3dsmax. Check the path where

3dsmax is installed and correct it if needed. Press setup to Continue.

Start the VRayPatternRegistration32x.exe or VRayPatternRegistration64x.exe utility (for 32-bit

or 64-bit systems accordingly)


9/16

Choose the hard disk to be linked with the VRayPattern license (linking with external USB

storage, Flash drives and network drives is not supported).

Press the Get Your ID File button and save *.id file on your hard disk under any name you

like.

.


10/16

Send this file to [email protected] (or your reseller). Please attach copy of you receipt to

avoid any delays in communication.

In the nearest time (usually within 24 hours) you will get an email from us (or your reseller) with

*.key license file attached. Save this file on your hard disk. Start again

VRayPatternRegistrationXX.exe utility and press the Apply Key File button.

In the dialogue box select the *.key file you received from us. With this registration procedure is

over.

In case of license malfunction and errors (which can be caused by disk formatting, reinstallation

of the operating system or components replacement) you are free to address the developer at any

time. Please make sure you download latest version from our forum and generate new *.ID file.

Send it to [email protected] to get your updated *.Key file

However, in case of total replacement of a PC new license is not provided more often than once

in half a year.

ATTENTION! Please always try to email from the same email address you used when you

purchased the plug-in. If we cant find your e-mail address from which you sent the ID file

in our database and there is no explanation and receipt or order number in you email, your

request may not be processed!


11/16

Please always attach you receipt or order number to avoid any delays in communication.

Uninstall.

To uninstall VrayPattern delete VrayPattern.dlo from \Plugins\VRayPlugins in you 3ds max

installation location.

Installing for network or distributed rendering.

For network rendering just install the same file VrayPattern.exe. Installation procedure is the

same as for the Workstation, but skipping Registration process. Rendernode version does not

require registration.

Submission for network or distributed rendering should be done from the PC with the registered

Workstation version of VrayPattern. The rest of render nodes involved in the network ordistributed rendering can have only Rendernode versions of VrayPattern installed.

Each VrayPattern license comes with unlimited render nodes.

VRayPattern Creation.

VRayPattern can be found in Objects under VRay

Interface.


12/16

On/OffEnabling and disabling an object.

From Current Scene- Object to be propagated is taken from current scene.

From File- Propagating geometry will be taken from another 3ds Max file. The file should

only contain one geometry object. Also in the file may be only one configured VRayPattern to

get all settings.

Library browser


13/16

Browser allows you to see the preview of max files which VRayPattern can use as the

geometry for propagating. To create a preview create an image in jpg format size 160x100 pixels

with same name as 3ds max file and place the image in same folder where the 3ds max file islocated .

The browser can remember the current path of the library, for this you need to click Save

Library Path. To return to the library path, you must press Move to Library Path.

Pattern Renderable- Quick way to turn off the visibility in rendering of the original object

of propagating.

Geometry Bias- Minimum passage distance of the ray after reflection from the geometry,

within which all other ray intersections with the geometry are ignored. If this parameter is 0,

the object will cast shadows on itself and will get covered with spots.

Crop Size- Size of the crop box of propagated geometry. All objects outside of the box areignored. Crop box also defines the repeating period of the geometry.

Height - Height multiplier of the propagated geometry.

Shift- Displacement of the geometry against surface normals, which is covered by

propagated geometry.

Reset Crop Box- Reset crop box to default starting position.

Fit Crop Box- Fit crop box within geometry saving rotation

Controlling crop box.


14/16

Crop box can be moved, rotate and scale. The cross with arrow shows position of the planeon which geometry will be multiplied. This position can be controlled with Shiftparameter.

Surface-. Surface on which geometry will be propagated.

Surface Renderable- Ability to quickly switch visibility of the surface in render.

Map. Channel- Map channel on the basis of which the geometry will be propagated.

Real World Scale- Work in real scale.

Tiling U/V- Mapping multiplier by U/V axis.

Polygon ID- Range of polygon IDs of the surface on which propagation is happening.

Random Segment Count - Enables to split multiplying geometry into several parts and

multiply these parts randomly on surface elements.


15/16

Preview

Dummy Size- Dummy size

Texture Size- Size of the generated texture. If the crop box dimensions are not proportional

(non-square projection) the size of the resulting texture may be different from the set value.

Make Preview Texture- Generation of textures for the preview. This texture can be used in

the viewport, in order to understand the scale of propagated geometry. To do this, save thegenerated texture on the hard drive and apply to the surface with standard tools of the material

editor in 3ds max

Limitations

Currently there is no support for smoothing groups of the surface of propagated object. This

can lead to visible edges on curved low polygon surfaces. We recommend using high polygon

objects for reproduction. We hope to find ways to solve this problem in future versions.
